Strategic Narrative Overview
On 23 November 1915, the Serbian government and supreme command decided to retreat across the mountains of Montenegro and Albania toward the Adriatic coast. The column included King Peter I, soldiers, prisoners of war, and hundreds of thousands of civilians. Harsh winter conditions, starvation, disease, and enemy raids — including aerial bomb attacks on the retreating columns — inflicted devastating losses throughout the crossing between November 1915 and January 1916.
01 / The Origins
In late October 1915, Germany, Austria-Hungary, and Bulgaria launched a coordinated offensive against Serbia. Outnumbered and caught between converging enemy columns, the Royal Serbian Army was forced southward. France and Britain landed four divisions at Salonika to assist, but Bulgarian forces blocked the relief effort in the Vardar Valley. By November 1915, the Serbs had been pushed into the Kosovo plain with no viable route of escape except westward through the mountains.
03 / The Outcome
Of approximately 400,000 who set out, around 180,000 reached the Adriatic and were evacuated by Allied ships to Corfu, where a Serbian government-in-exile was established under Prince-Regent Alexander and Nikola Pašić. A further 11,000 died afterward from the ordeal's effects. The reconstituted Serbian Army subsequently joined Allied operations on the Salonica front and later contributed to the liberation of Serbia.
